LUBRIGATOR.. i

Specification of Letters Patent.

Patented Jan. 29, 1907.

Application filed Tune l2, 196. Serial No. 321,372.

To fir/ZZ whom, t nca/y cncc'u:

Be it known that I, WILLIAM S. PATTER- soN, a citizen of the United States, residing at Salt Lake City, in the county of Salt Lake and State of Utah, have invented new and useful Improvements in Lubricators, of which the following is a specification. My invention is designed to lubricate the bearings of automobiles, railroad-cars, and all similar bearings. It is automatic in its action, needing only to be supplied with the lubricant when the oil-reservoir is empty.

The accompanying drawings fully. illustrate the device, its various features being j referred to by letters of reference, similar letl ters denoting corresponding parts in the several views.

In the drawings, Figure 1 is a side elevation, partly in section, of the device; Fig. 2 is a reduced side elevation of the oil-cup, and Fig. 3 is a view 'taken between linesx x and y y in Fig. l and showing a modification of a l washer.

The letter-A designates a bearing to be lu- I bricated andthe adjacent parts. v j

B is an oil-box, having a duct b through its bottom. This duct leads the oil from the box to the bearing A.

C is the oil-cup adapted to fit into the oilbox B and is' provided with external lugs c, which rest upon the edge of the box B and maintain the cup 'in proper position.

K is the cover of the oil-reservoir c. It is provided with a vertical extension lc to fit into the cup and with vertical extensions 7c at each corner to contact with the interior corners of the cup. A perforated lug 7c on the top of the cover is adapted to be connected with a chain.

The oil-cup C is preferably molded in one piece, its upper portion having the reservoir c for the lubricant. In its lower part is formed an opening D, in which is located a thick disk E, having a vertical perforation e. On account of the varying thickness and orosity of the Washers, which are used eneath this disk, AI prefer to make the disk vertically adjustable in the-opening D, and

this is preferably accomplished by forming a thread on the periphery of the disk to enya e a thread in the upper part d of the openmaterial, toretard and regulate the flow of j oil through the duct e in the disk.

Normally the washer 7L is held against the disk E by the pressure of the spring g." A dlct i leads downward from the cup into the oi -box.

In the modification shown in Fig. 3 the diameter of the washer 7L is less than that of the opening D. -The washer is preferably secured to theplunger by a screw t. head f is provided with shortlateral pins t,` which by contact with the sides of the opening D keep the plunger in position. When the washer h is used, the oil passes over the edge of the washer in larger quantities than when the form 7L is used. y

This device is made operative by thejolting or jarring of the car when in motion, by which means the plunger alternately recedes from and presses' against the washer L or 71,', and so permits the passage of oil from the cup to the bearing. of the reservoir prevents any foreign matter from reaching the bearings.

What I claim, and desire to secure, is-

l. In a lubricator, an oil-cup having a thick bottom with a vertical opening therein, a perforated disk in said opening, a springupported plunger reciprocating vertically e tween said plunger and said disk and a duct at the bottoni of said opening as specified.

2. In a lubricator an oil-cup seated in an oil-box and having a thick bottom with a vertical opening therein, a vertically-adjustable perforated disk in said opening, a

spring-supported plunger reciprocating ver- The ow said disk, an oil-permeable washer be- A lter d in the bottom i IOC en oil-cup seated in said boX and having an seid washer upon said `plunger and a duet 1o oil-chamber with a central opening in its botopening into said Oil-box as herein set forth. tom, having its upper part threaded, a filter l In testimony whereof I affix my signature covering said opening, a threaded cllisk ,in n presence of two subscribing witnesses.

seid opening having a vertical @henne therethrough, a plunger below said disk, a spring l XVLLAM S' PATTERSON supporting said plunger, a washer of less d- Wltnesses: ameter than that of the opening between l J. XV. BOND, said plunger and said disk, means to secure F. A. MOYLE.
